SPECIFICATION forming partof Letters Patent No. 518,583, dated April 24,1894. Application filed August 31,1893. Serial No. 484.423. (No model.)

To all whom it may concern:

Be it known that we, JAMES T. BRIEN and THnoDoRE R. BRIEN, citizens ofthe United States, residing at Hoosick Falls, county of Rensselaer, andState of New York, have invented certain new and useful Improvements inSoil-Pipes, of 'which the following is a speciication.

Our invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and the letters ofreference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a central 1ongitudinal section of thenfaucet end of a section of soil pipe, the spigot end being broken awayfor convenience in illustration. Figs. 2 and 3 are similar views showingour invention in modified forms. Fig. 4 is an end view showing thewrought-metal band before the pipe is cast upon it.

It is well known to those skilled in the art that joints formed in soilpipes must be made of a durable character, and sufficiently tight toprevent the escape of sewer gas therefrom. Such joints are usuallyformed by inserting the spigot end of one section in the hub, orenlarged portion formed on the faucet end, of another section,andcalking the space between the walls of the spigot `and faucet ends ofthe pipe sections with lead forced therein by a cold chisel or similartool subjected to the blows of a hammer. When the lead is properlycalked to produce a gastight joint, the pressure upon the inclosingfaucet-end is very great, being frequently sufficient to burst or crackthe pipe. We have ascertained that the faucet end of the pipe can besufficiently strengthened by casting the same upon a wrought-metal band.The wroughbmetal, being much more tenacious than the castmetal and beingin close contact therewith, largely increases its power of resistancewithout increasing its bulk, thus eliminating the danger of leakycracks. The band may be a wire, or in any desired form, and of any kindof metal having comparatively great tenacity.

Referring to the drawings, A#- represents a bandwhich iiares outwardly,as shown in Figs. 3 and et. The pipe B has its enlarged, or faucet endB'- cast upon the inner side of the band, as shown in Fig. 3. The bandthus strengthens the pipe like a hoop and is anchored onto the pipe, sothat it cannot be removed, by its inner thickened end A- produced by itsbeveled form.

In'Fig. 1, the band A2- is inclosed by the cast-iron which is cast uponboth the exterior and interior surfaces of the band, which is anchoredby the inner thickened end A3.

In Fig. 2, the band A4 is inclosed by the cast-iron cast upon itsexterior surface, leaving the interior surface of the band exposed.

The exterior surface ofthe band is beveled to produce the innerthickened end A5 by which the band is anchored to the cast-iron.

The band may be provided with any known form of anchorage.

We are thus able to produce a new article of manufacture which not onlyeliminates the costly item of breakage, but insures a safer and moredurable joint without increasing the bulk of the pipe. t

I-Ieretofore the workman has favored the weakness of the pipe at theexpense of the efficiency of the lead packing to prevent leakage of gas.

With our improved pipe, the joints can be calked more quickly as well asmore securely, because harder blows can be delivered with thecalking-iron and hammer without fear of injury to the pipe.

By having the reinforcing band ilush with the castmetal and prominentlyexposed at the outer edge of the faucet-end of the pipe, as shown,glancing blows of the calking-iron or hammer will be received by thewroughtmetal band instead of by the cast metal of the pipe as heretoforeto the great injury of the latter.

What we claim as new, and desire to secure by Letters Patent, is

1. A cast-iron soil-pipe having its faucetend cast upon an annulartenacious-metal In testimony whereof we have hereunto set band anchoredand embedded in the castour hands this 22d day of June, 1893. metal,substantiall as described. 2. The combinatyion with a cast-iron soil- Y5 pipe, of a Wrought-metal band embedded and anchored in the faucet endof the pipe and Witnesses: exposed at the outer end thereof, substan-WM. H. STARRETT, tially as described. C. F. W. SMITH.
